The head of a global arms watchdog said today that "incontrovertible" test results from an alleged chemical strike in Syria showed sarin gas or a similar substance had been used.
Samples from 10 victims of the April 4 attack on Khan Sheikhun analysed at four laboratories "indicate exposure to sarin or a sarin-like substance," said Ahmet Uzumcu, head of the Organisation for the Prohibition of Chemical Weapons.
The suspected attack on the rebel-held town in Idlib province killed at least 87 people, including many children, and images of the dead and of suffering victims provoked global outrage.
Samples had been taken from three people who died in the attack, and were analysed at two OPCW-designated laboratories, Uzumcu told delegates to the OPCW's executive council today, according to a statement from the watchdog.
Another set of bio-medical samples from seven people being treated in hospitals were also analysed in two other labs.
"While further details of the laboratory analyses will follow, the analytical results already obtained are incontrovertible," Uzumcu told the meeting of the body's executive council which resumed today at its headquarters in The Hague.
A fact-finding mission set up by the OPCW is ready to deploy to the town "should the security situation permit," he said, adding the team was continuing to conduct interviews, and collect samples.
The executive council is to meet again tomorrow to vote on a draft decision which is being discussed.
